CeNav is a lightweight and simple-to-use jQuery plugin for create a nice-looking multi-level dropdown menu from nested HTML unordered lists.

How to use it:

1. Create nested html lists for the dropdown navigation.

<header>
  <nav>
    <ul class="top-level">
      <li><a href="#">Home</a></li>
      <li><a href="#">Page</a></li>
      <li><a href="#">Categories <span></span></a>
        <ul class="sub-menu">
          <li><a href="#">Item 1</a></li>
          <li><a href="#">Item 2 <span></span></a>
            <ul class="sub-menu">
              <li><a href="#">Item 1.1</a></li>
              <li><a href="#">Item 1.2</a></li>
            </ul>
          </li>
          <li><a href="#">Item 3</a></li>
          <li><a href="#">Item 4</a></li>
        </ul>
      </li>
      <li><a href="#">Contact</a></li>
      <li><a href="#">About</a></li>
      <li><a href="#">Blog</a></li>
    </ul>
  </nav>
</header>

2. Style the nav menu in the CSS.

header {
  background: rgba(0, 0, 0, .5);
  height: 60px;
  padding: 15px;
}

ul { list-style-type: none; }

li { position: relative; }

ul.top-level > li { float: left; }

ul.top-level > li a {
  padding: 0 10px;
  line-height: 30px;
  display: block;
}

a {
  display: block;
  text-decoration: none;
  color: rgba(0, 0, 0, .75);
}

span {
  float: right;
  margin-left: 5px;
  width: 30px;
  height: 30px;
  line-height: 30px;
  text-align: center;
  background: rgba(0, 0, 0, .1);
  transition: .2s linear transform;
}

span:before {
  content: "\f107";
  font-family: FontAwesome;
  font-size: 14px;
}

ul.sub-menu {
  position: absolute;
  top: 45px;
  left: 0;
  width: 200px;
  background: rgba(0, 0, 0, .5);
  padding: 5px;
  border-bottom: 5px solid rgba(0, 0, 0, .75);
  display: none;
}

ul.sub-menu li a {
  display: block;
  padding: 5px 10px;
}

ul.sub-menu li a span { transform: rotate(-90deg); }

ul.sub-menu li a span.close { transform: rotate(90deg); }

ul.sub-menu li ul.sub-menu {
  position: absolute;
  top: 0;
  left: 195px;
}

3. The ESSENTIAL CSS styles for the nav menu.

span.close { transform: rotate(180deg); }

ul.active { display: block; }

4. Load jQuery library and the jQuery CeNav plugin's script at the end of the document.

<script src="//code.jquery.com/jquery-3.1.1.min.js"></script>
<script src="jquery.plugin.cenav.1.0.js"></script>

5. Initialize the plugin and done.

$('ul.top-level span').cenav();
